Abstract

Embodiments of the invention provide electrical power management apparatus for a motor vehicle comprising: a primary power storage device for powering an engine starter device; a vehicle electrical load; a secondary power storage device for powering the vehicle electrical load; and a solid state primary diode portion coupled between the primary power storage device and the vehicle electrical load, the primary diode portion being operable to allow a flow of current in a forward direction therethrough from the primary power storage device to the vehicle electrical load when the starter device is not in use and to prevent a flow of current in a reverse direction therethrough from the secondary power storage device to the engine starter device when the starter is in use.
